Patented Dec. 12, 1911 I To all whom it may concern! Be it known that I, Emma L. Sma- MAN, a citizen of the United States, residing without departing from the principle of the invention, which may be understood by referring to the drawings and the following I machine; (6) the planes or wings; (p) theat 'Westerly, in the county of Washington and State of Rhode Island, have invented a certain new and useful Improvement in Alaeplanes, of which the following is a specificatio This invention relates to 'a multiple winged flying machine having wings so arranged that they serve both as a sustaining plane surface, and also as a means of propulsion; this being accomplished in the manner shown in the accompanying drawings.

"It will be apparent that the particular form of construction shown may be altered,

. upper part of wing working rods; (d) the steering wheel; (e) the steering handles; I (72.) shows movable seats.

In operation, it is intended to combine foot power, with a gasolene motor in beginning an ascent or in descending, or at other times as may be necessary. Both motor and foot power drive the rear wheels of the machine, combined or independent action being secured I by means of the well known coaster-brake as usd in motor bicycles.

Mounted on the rear wheels is. an eccentric or-similar device for transmitting motion to the wings through the working rods (0) so that the wings are operative at all times whether. machine is in the air or on the ground, this being an advantage in beginnin an ascent or in alighting after a flight. 1 Ti.

e seats (11.) are arranged to slide back and forth on slides (m) so that the center of load may be varied in order, to balance or otherwise control the machine.

. The steering wheel (d) is constructed 'Of two aluminum plates, suitably fastened and having a rubber tire on the rim thereof.

while in the air as well, as a steering wheel while on the. groundQ This steerin is connected with the steeping hanfi by thereach rod (Z).

Mounted on top of the framework (a) and reaching across the machine are work shafts (n) journaled in suitable journals at the top of each upright frame member. At I the ends of these work shafts are levers (g) This wheel is intended to act as a rudder wheel pivotedto a connecting rod" (f) which transmits motion to all three work shafts simultaneously from the diagonal working rod (0) Keyed to these work shafts are the wooden spines. (In) Figs. 2 and 3, suitably bushcd, and having attached to them a hinged wire frame (0) Fig. 3 to which the wlng surfaces (6 composed of suitable fabric, may be attached by lacing, or other suitable means, the whole constituting the wing, which is the essential feature of my invention. In detail, this wing and the manner of its working is shown more clearly 'in Figs. 3, 4 and 5. I

In Fig. 3, the wooden spine is shown 'irrthree 'sitions, .with a portion of the wiork shaattached, and the wire frame a so.

In Fig. 4, the wing is shown with the, cover on, and as it a pears at the end of its downward stroke. 1g. 5 shows the posi- 'tion-of the win at the end of its upward movement, the otted lines indicating what may be the osition of the wings at the beginning'of t e next downward stroke.

The action of a single wing being understood, it will be clear that'this invention embodies an entirely new principle in flying machines; i. e. the collapsing wing feature in which the-rapid movement in a downward and rearward direction results in an automatic opening and closing of the wing, by reason of the variation in the pressure exerted .by the air on the under surface, or the upper surface of the wing, as the case may be, during upward and downward movement. The resultant efl'ect of the rapid opening and closing of a multiple numberof wings construct-' ed as shown, is a lifting and at the same time a pushing forward of the machine.

Herein lies the difference between my in- -vention and the other devices which have been invented for the purpose. In my invention, aside from the source ofpower, or
